The Chevrolet Avalanche was a four-door sport utility truck. It was sold by General Motors' Chevrolet brand in the United States. The Avalanche was first made in 2002 in Silao, Guanajuato, Mexico and the second generation was first shown at the Chicago Auto Show in February 2006. It was named after the sudden collapse of mountain snowpacks that are known as Avalanches. There have been two generations of the Chevrolet Avalanche with the second one being made in 2007, until it was discontinued in 2020.
